A bill of exchange is a formal, written, unconditional order used primarily in international trade that binds one party to pay a fixed sum of money to another party on demand or at a predetermined future date. It serves as a legal instrument to facilitate credit transactions between buyers and sellers.

A bond is a fixed-income instrument that represents a loan made by an investor to a borrower (typically corporate or governmental). Bonds are used by companies, municipalities, states, and sovereign governments to finance projects and operations. Owners of bonds are debtholders, or creditors, of the issuer, and they receive periodic interest payments and the return of the face value upon maturity.

Speculative bubbles occur when asset prices rise significantly above their intrinsic value. This phenomenon is often driven by the 'greater fool theory,' where rational investors purchase overvalued assets, not because they believe the asset is worth the price, but because they expect to sell it to another investor at an even higher price in the near future, creating a feedback loop of rising prices.

Plastic money refers to the hard plastic cards used in place of actual cash for making purchases. Credit cards, along with debit cards, are the most common forms of plastic money. They allow users to access funds or credit lines electronically, providing a convenient and secure alternative to carrying physical currency or writing paper-based instruments like cheques.

The term 'plastic money' refers to the physical cards, typically made of plastic, used as an alternative to cash or checks for making payments. Credit cards, debit cards, and prepaid cards fall under this category. They facilitate electronic transactions by accessing lines of credit or bank accounts, providing a convenient and secure method for consumers to purchase goods and services without carrying physical currency.

A 'bounced' check occurs when a bank refuses to honor a payment because the account holder lacks sufficient funds to cover the transaction amount. This is a common term in banking and finance to describe dishonored checks.

A bearer cheque is a financial instrument that is payable to the person who physically presents it to the bank. Unlike an order cheque, it does not require a specific payee name to be endorsed, making it transferable by simple delivery.

A term certificate, often referring to a Certificate of Deposit (CD), is a financial product where the principal is held for a fixed term and becomes payable upon the maturity date. It functions similarly to a term bond by locking in capital for a specific duration in exchange for interest.

Interest rates on bonds are heavily influenced by default risk. Startup companies are inherently riskier than established corporations or sovereign governments. To compensate investors for the higher probability of default, startups must offer a higher interest rate (risk premium). Conversely, government bonds and blue-chip corporate bonds are considered safer, leading to lower yields.

A manipulated market occurs when individuals or groups artificially influence the price or volume of a security to create a misleading impression of market activity. This practice is illegal in most regulated financial markets as it misleads investors and undermines market integrity.
